The board heard arguments via telephone in the tribe's case against Powertech Uranium Corp.
The tribe wants further studies to ensure sacred and cultural sites in the Black Hills won't be harmed by the mine.

The Nuclear Regulatory Commission
awarded an operating license to Powertech to restart uranium mining in an area about 60 miles west of the reservation border. The Edgemont uranium district is also close to the Wyoming border and to the Nebraska border.

The Atomic Safety and Licensing Board plans to make a decision in a few days, the Associated Press reported.
